To ctZZ whmn it ntcty concern:

Be it known that 1, CHARLES E. Enronson, a citizen of the United States,residing at Chicago, in the county of Cook and State of lllinois, haveinvented certain new and useful Improvements in MetallicSliding Windows;and l[ do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon", which form a part ofthis specification.

This invention relates to improvements in sliding windows, and refers,first, to an improved weatherproof connection between the side membersor jamhs of the window-frame and the windowsash, and, secondly, to animproved automatic thermally-actuated releas ing device for thewindow-sash of that class wherein the window-sash and theircounterbalancing-weights are so proportioned that when the sashes arereleased they are closed either by an overbalance of the weights or thesash, depending upon whether it be the upper or lower sash.

My improvements are herein shown applied to windows of metallicconstruction; but in so far as they relate to the means for providing aweather-tight connection between the sash and frame the parts may bemade of other suitable material.

As shown in the drawings, Figure 1 is a side elevation of a windowprovided with my improvements, showing the lower sash partly raised,parts of the sash and frame being broken away to better show theconstruction. Fig. 2is a vertical section thereof. Fig. 3 is atransverse section taken through the window frame and sash at thevertical plane of the pivot-bolt for the guide-bar 7). Fig. A is afragmentary perspective view of a portion of the side member of thewindow-frame and the weather-strip in position therein. Fig. 5isafragmentary side view with parts broken away of the lower one cornerof the sash and a portion of the adjacent side member of thewindow-frame. Fig. 6 is a partial bottom plan view of the lower rail ofone of the sashes.

As shown 1n the drawings, A A designate the side members, and A A thetop and bottom members, respectively, of the windowframe, and B B thetwo sliding window-sashes therein. Said window frame and sash members,asherein shown, are constructed of sheet metal, the metal plates orstrips of which they are composed being suitably folded to constitutehollow or tubular members connected together in any suitablemanner. Thesashes B are counterweighted by the usual weigl'its A, the chains a ofwhich are trained over pulleys A" and are attacl'ied at their other endsto the window-sashes. The inner walls of the side members A of thetubular side members of the window-frame are provided with guide groovesa to receive guide-bars 6, extending laterally from the stiles of thesashes. As herein shown, said guide-bars 7) of the sashes are littedinlongitudinal grooves 7), which are formed in the outer walls of thetubular stiles of the sashes. In case the sashes be made of otherconstruction the said guidebars may be otherwise attached thereto. Eachof said guide-bars is held in placein its groove 1) of the stiles bymeans of a screw 7) near the top of the stile, which extends looselythrough oneside of the stile and through the bar and has screw-tln'eadcdengagement with the walls of the grooves I). As herein shown, thecounterweight-chains are fastened to the upper ends of said bars, whichextend a distance above the sashes.

(l designates a weather-strip fitted in each guide-groove a of thewimlow-frame and extending from the top to the bottom thereof. Saaidstrips are made of general U form in cross-section and are fitted withtheir closed or U-shaped parts in said guide-grooves. The guide-barsb ofthe sashes lit closely and slide endwise in said channeled or lJ-shapeweatherstrips. The weather-strips are made of sheet metal possessingsome resiliency, tempered sheet-brass being an approved material. .l.heyare provided at their side margins with reversely-bent flanges c, whichare located outside ofthe grooves a and the extreme margins of whichbear against the inner faces of the frame members at the sides of thegrooves therein in the manner more clearly shown in Figs. 3 and 4t.hleans are provided, hereinafter to be described, which force theguidebars Z2 laterally outwardly into engagement with theweather-strips, the side margins of said bars closely fitting thebottoms of the j channel or U-shaped weather-strips. The

ture, so as to afford protection against lire engagement of the sashguide-bars with the bottom or closed parts of the weather-strips tendsto force said weather-strips into the grooves a, said grooves being madedeeper than the strips, and such tendency to force the strips into thegrooves is resisted by the spring action of the reversely-bent flanges cof said strips. The effect of this action is to provide a tight jointbetween the inner mar gins of the sash guide-bars and the bottoms of theU-shaped weather-strip and also between the side edges of said stripsand the inner side faces of the window-frame. It will thus be seen thatthe resilient or yielding parts of the weather-strips 'to wit, thecurved portions 0-are located mainly outside of the grooves. Theconstruction thus described maintains a constant pressure. against theguide-bars of the sashes on the one side and the frame on the other,thus maintaining always a tight joint between the sash and frame, whilepermitting the sash to be moved without the application of great forcethereto. The said pressure exerted between the sash and weather-stripsacts to hold the sashes open so long as said pressure is maintained.When the pressure is released, the overbalance of the lower sash or theover-balance of the weights of the upper sash has the effect of closingthe window.

The means for applying pressure to force when closed. The purpose of theautomatic thermally-actuated releasing-device is to afford means wherebythe window shall automatically close in the event of a tire occurring inthe vicinity of the window, and thereby protecting the interior of thebuilding.

It is obvious that the structural details of the window herein shown maybe considerably varied without departing from the spirit of myinvention, and I do not wish to be limited to such details except ashereinafter made the subject of specific claims.

I claim as my invention 1. The combination with a window-frame memberprovided with a longitudinal guidegroove and a sash member, of aweather-strip of general U form in cross-section fixed stationary insaid groove and bearing at its side margins against the inner face ofthe frame member at the lateral sides of said groove, and a longitudinalguide extending laterally from said sash member and entering and havingsliding engagements with the channel of said strip.

2. The combination with a window-frame provided with a longitudinalguide-groove and a sash member, of a channeled weather-strip fixedstationary in said groove and bearing at its side margins against theinner face of the frame member at each lateral side of said theguide-bars outwardly into binding-contact with the weather-stripsconsists, as herein shown, of clamping-screws D, located one at eachlower corner of each sash and bearing against the inner margins of theguide-bars b at their lower ends. Said clamping-screws havescrew-threaded engagement with brackets D, attached to the sashes andlocated, as herein shown, in recesses in the bottom face of the lowerrails of the sashes. Said brackets have horizontal and vertical arms,the screws extending through the vertical arms. The brackets arefastened to plates (Z, aflixed to the window. Thus when pressure isapplied through the medium of said screws to the bars it presses thelower ends of the bars outwardly into close contact with theweatherstrips, affording such pressure as is required to maintainweatherproof joints and to counteract the overbalancing effects tendingto close the sashes.

The brackets D are fastened to the plates (Z of the sashes through themedium of a solder which fuses at a low temperature. Upon the fusing ofthe solder, therefore, the brackets carrying the clamping-screws arefree to fall away from the sashes. When this occurs, the pressureagainst the bars 6 is released, so that the sashes are free to close,the lower sash the sides of the groove therein, a guide-bar extendinglaterally from said sash member and entering and having slidingengagement with the channel of said weather-strip, the sash memberengaging the curved parts of the strip outside of the groove.

L. The combination of a window frame member provided with a longitudinalguidegroove and a sash member, of a weather-strip of U form incross-section fitted in said groove, the side margins of which bearagainst the inner face of the frame member at the sides of said groove,a guide bar extending laterally from the sash member and having slidingengagement with the channel of said weatherstrip, and means foradjusting said bar laterally on the sash member.

The combination with a window-frame member provided with a longitudinalguidegroove and a sash member, of a spring sheet metal weather-strip ofU form in cross-section fitted in said groove, the side margins of whichbear against the inner face of the frame member at the sides of saidgroove, a longitudinal bar extending laterally from said sash member andhaving sliding engagement with the channel of said strip, and meanscarried by the sash member for forcing the said bar laterally into closeengagement with said weather-strip.

6. The combination with a window-frame member provided With alongitudinal guidegroove and a sash member provided with an opposinggroove, of a sheet-metal weatherstrip of U form in cross-section fittedin said guide-groove and bearing at its side margins against the innerface of the frame member at the sides of said groove, a guide-bar in thegroove of said sash member, extending laterally therefrom and havingsliding engagement with the channel of said weather-strip, and means forforcing said guide-bar laterally into close-fitting engagement with saidweatherstrip.

7. The combination with a Window-frame member provided with alongitudinal groove and a sash member provided with a registeringlongitudinal groove, of a spring-metal weather-strip of U shape incross-section fitted in said frame-member groove and hearing at its sidemargins against the inner face of the frame member at the sides of saidgroove, a guide-bar in the groove of the sash member, a pin extendingthrough the sash and through the upper end of said bar to hold the barin place, and a clamping-screw carried by the lower part of the sash andacting to force the lower end of said bar into close-fitting engage mentwith said Weather-strip.

8. The combination with the upright member of a Window-frame provided atits inner face with a guidegroove, a spring sheet-metal, channeledweather-strip fitted stationary in said groove, of a sliding window-sashmember provided with a longitudinal guide-groove,

' a bar in said groove pivoted between its ends to said sash member andextending laterally from the sash member and having sliding engagementwith said channeled weather-strip, and a rigid clamping device carriedby said sash member and bearing against one end of said pivoted bar toforce the same into engagement with the spring-metal channeledWeather-strip, said clamping device embracing a fusible joint.

9. The combination with the side members of a window frame provided withguide grooves and a widow-sash, of weather-strips of U form incross-section fitting in said grooves and the side margins of which bearagainst the inner faces of said frame members at the sides of saidgrooves, longitudinal guidebars extending laterally from the sashes andhaving sliding engagement with the channeled weather-strips,balancing-weights provided with chains which are attached to said sash,and clamping devices carried by the sash and bearing against the lowerends of said bars to force the same into close-fitting engagement withsaid weather-strips, said clamping de- Vices being connected. with thesash by means embracing fusible joints.
